Specification of Letters Patent.

Patented Mar. 18, 1919.

To all 'whom 'it may concern:

Be it known that I, RUSSELL R. TEMPLE, a citizen of the United States, residing at Santa Paula, in the county of Ventura and State 'of California, have invented certain new and useful Improvements in Pumping Apparatus, of which the following is aspecification.

This invention relates to pumping apparatus, and more particularly to improvements in apparatus designed for pumping great depth below the surface of the ground.

The invention will hereinafter be described with relation to its application to the hollow sucker rod used in connection with oil pumping apparatus, in which the hollow,l

weight of the column of liquid which it is raising to the surface of the ground.

Other objects will be in part obvious from theannexed drawing and in partlindicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts and in the unique relations of the members and in the relative .proportioning and disposition thereof, al1 as more completely outlinedherein.

To enable others skilled in theart so fullyTA to comprehend the underlyin features thereof that they may embody t e same by the numerous modifications in structure and relation contemplated by this invention, a drawing depictlng a preferred 'form has been annexed as a part ofthis disclosure, and in such drawing like characters of reference denote corresponding parts throughout all the views, 'in' which .Figure 1 'is a sectional elevational semidiagrammatic view of the complete apparatus Fi 2 is a vertical sectional view of the con g and check Valve of the hollow suc er rod;

with a hollow sucker r Fig. 3 is a perspective view of certain detached parts of the check valve.

Referring now to the drawings in detail, and more particularly to Fig. 1, 5 denotes the outer casing or tubing which is lowered into a drilled hole in the ground to the full depth of the well. Ati lthe lower end of this tubing. is a pump -6 of any desired hollow piston rod type. This ump is connected od) 7, which is reciprocated within the casing 5 in any well known manner. The pump itself is provided with one or more check valves 8, as indicated, of such construction that as the pump movesdownwardly the oil -or liquid to'be pumped will pass up through the opening, and on the up-stroke willbe prevented from assing back through the openings by the ba l valves, as indicated. This constant reciprocation of the pump will cause the oil to pass up through the sucker rod andv flow out through the (top,

As above stated, it is one of the objects of the present invention to rovide an apparatus of this general c aracter with means adapted to relieve the pump from supportingV the complete column of oil extending' to the surface, and with this idea in mind a plurality of check valves are pro vided in the sucker rodat regular intervals, say one or two hundred feet apart, ada ted to support a section of the column o oil thereabove. This check valve-is shown in .Fig 2 of the drawings, and is v'preferably interposed between two adjacent sections of the sucker rod 7. These sections are threaded at their ends and coupled together by means of a couplin member 10 as shown. This coupling mem er, which is threaded throughout its length, has centrally disposed therein a cage, 11, the lower art of which is threaded! at 12 to co-act with the threads of the coupling member, 'and is also internally threaded at 13 to receive the valve seat member 14, the latter being rovided with a bevel valve seat 15, with w ich a correspondingly shaped valve member 16 is designed to co-act; A ball valve may be used if desired. The valve-16 is provided with a plurality of downwardly projecting legs 17, adapted to iit within the valve seat member 14 and be guided thereby in its u and down movement within the cage 11. 1

yach` valve 16 is preferably provided withl a small leak hole 18 in the top to better insure its setting into place and give it a freer action. These valve members are all substantially et the same construction, size and material, according to requirements, and it is believed that the method of use and operation of a device of this character is clear from the above description. lt may he stated however that alter the parts are assemloled in the usual manner, and occupy the position substantially as shown in wFig. l, the hollow sucker rod is reciprocated, which causes the oil or other liquid to pass upwardly through the pump and within the sucker rod 7. lThe valve l@ operates simultaneously with the operation of the valves on reeiproeation of the sucker rod, and each one is designed to su port 'the Column oi liquid immediately t ereahove and below the nent above check valve. rl"he parts are oi simple and practical construetion, and they may he easily applied to systems now in general use without material modication or alteration.

lt will oe-noted that when it is desired to remove the member lei, as for instance when grinding the valve seat l5, the lower section-of the hollow sucker rod or pipe 7 may he removed and the member ld unserewe'd without disturbing the cage.

l realize that eonsiderahle variation isy possible in the details of construction and arrangement or parts without departing 'from the spirit of my invention, and l theregore do not intend to limit mysela to the speeidc form shown and destrioedl designee threaded externally and arranged to engage internal threads on the cage for holding the valve seat in position, and a valve disposed within the cage and arranged to engage the valve seat.

2. 'lhe combination of a pair of pipe sections having threaded ends, a threaded coupling arranged to engage the threaded ends of the pipe sections for connecting them together, a cage comprising an upper open frame and a lower integral hollow cylindrical portion threaded externally for engaging the threads of the coupling, a hollow cylindrical member disposed on the interior of said lower portion and having a valve seat at its upper end, and a valve disposed within the cage and having guide members arrange-d to engage the interior of the cylindrical member carrying the valve seat.

ln testimony whereof l ax my signature in presence of two witnesses.
